8 Claims.

My invention relates to plumbing, and more particularly to unitary structure, including a drain tank, which is adapted to be connected to the various plumbing fixtures of a bathroom and to the sewerage and water supply systems of a building.

In accordance with my invention there is provided a wall panel or section within which is disposed the drain tank andwhich carries the necessary water and drain pipes. This panel is adapted to form a portion of a wall. The drain tank has a wall of sufiicient dimensions to receive the drainage of all of the plumbing fixtures in a direct way.

Further objects and advantages of my invention will be apparent from the following description, considered in connection with the accompanying drawing, which forms part of this specification and of which:

Fig. 1 is a side view, partially in cross-section, of a preferred embodiment of my invention;

Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a cross-sectional view on an enlarged scale taken on the line 3-3 of Fig. 1; and

Fig. 4 is a cross-sectional view on an enlarged scale taken on the line of 44 of Fig. 1.

Referring to the drawing, reference character tank It, in order to completely drain the tank, if necessary, as for purposes of repair.

The pipe 22 is carried by the panel and is arranged to be connected to th hot water supply system of the building. This pipe extends within the conduit I9 for the purpose of heating the air therein so that it will rise through the conduit I9 and pass into the upper end of the drain l8, which is adapted to be connected to a ventilation pipe extending through the roof of the building.

The upper part of the tank I4 is provided with an opening of substantial size which is normally closed by a cover member 23. The purpose for this opening is to permit cleaning of the interior of the tank and is preferably located entirely above the level of the liquid maintained in the Ill designates generally a wall section or panel and comprises a frame ll carrying wall boards 42 and I3 which are spaced apart so as to provide a hollow panel.

Disclosed within this panel is a drain tank H of generally rectangular shape, with the exception that the bottom is preferably inclined as shown clearly in Fig. 1. As will be seen, the length and height of this tank in the plane'of the wall section is greater than its thickness perpendicular to that plane. Tank I4 is provided with hooks I5 which engage the upper edges of a reinforcing strip 16, preferably of metal, which is carried by the frame II.

A conduit ll communicates with one end of the tank ll a short distance above the bottom and extends downwardly to join a vertically disposed drain pipe It. A conduit 19 communicates with the upper part of the tank and extends upwardly to join the drain l8. Preferably, conduits I1 and I! are integral with both the tank l4 and the drain l8, whereby a unitary structure is provided. A baflle 20 is provided Within the tank adjacent to the end of pipe l1 and is arranged to provide a liquid trap to prevent the entrance of sewer gas from the drain l8 into the tank. A

trap at the bottom of the tank.

The tank is preferably so arranged as to extend below the floor level 24. A floor drain 25, shown more in detail in Fig. 3 is arranged to discharge into the tank. This drain is preferably provided with a grating 26 which is sunk slightly below the floor level.

'A drain 21 communicates with the tank I! and with the outlet of a bathtub 28. If desired, the upper end of the drain 2lmay be funnel shaped, as is shown at 29, while the outlet of the bathtub may be provided with a packing 30 arranged to seat within the funnel. An overflow conduit 3| extends from drain 2'! to near the top of the bathtub.

A pipe 32, carried by the paneL is adapted to I be connected to the cold water supply system. Hot water pipe 22 and cold water pipe 32 are connected through suitable mixing valves 33 and 34 so as to supply water at the desired temperature to either the bathtub 28 or to a hose 35. This hose may be connected to a shower spray.

A drain 36 communicates with the upper part of tank l4 and is connected to the discharge of a wash basin 31. Water at the proper temperature is supplied to the basin through the mixing valves 38 and 39.

Should it be desirable to provide plumbing fixtures on the opposite side of wall panel l0, such as a kitchen sink, a drain connection 40 may be connected to the tank on the opposite side thereof from drains 25, 21, and 36.

A drain 4| is preferably integral with drain l8 and is connected to a toilet bowl 42 which is supported thereby and hence forms part of the unitary structure. A flush tank I3 is supported by the panel and connected to the bowl 42 by plug 2| may be provided at the lowest point of means of conduit 44. Tank 43 is connected to the cold water pipe 32 by means of a 1' fitting II. A baille 48 is provided in drain I. opposite the end oi conduit II for purpose oi preventing the suction, caused by the rapid flow oi water through the conduit 4|, from emptying the trap in the bottom of tank ll.

-It will thus be seen that I have provided a unitary arrangement which may be assembled at the -i'actory and shipped complete and ready for installation in a building. Included in this unitary arrangement are the drain tank and all connections required for the usual bathroom fixtures, which on place installation can be mounted in their positions in a simple way.

While I have shown and described a more or less specific embodiment of my invention, it is to be understood, that this has; been done for the purpose oi illustration only and is not to be considered as limiting the scope oi. my invention, which is to be determined by the appended claims.
